Abstract (en)

[origin: WO9119901A1] In a process for controlling the speed of an internal combustion engine after starting, the firing angle (ZW) is adjusted in the retard direction when a threshold speed (nS) is reached in order to reduce the output and to obtain the idling speed (nLL) without overrun. The threshold speed (nS) is a function of the temperature-dependent idling speed (nLL). The firing angle adjustment ( Z) is a function of the rate of variation of the engine speed.
